SUB2010-00003 Westwind Estates Subdivision Property Line Adjustment
Date:
To:
From:
The Transportation Division has reviewed the materials provided with the subject application.
The required findings and conditions outlined below are provided for your implementation into
the land use decision.
General
Finding: Approval of this proposal would allow Westwind Subdivision Lots 99,100 and 101 to
have their property lines adjusted.
TransDortation System ImDacts
Finding: Lot 99 gains size, and has no Transportation issues related.
Finding: Lot 100 "loses" 10 feet on the southerly side, but gains 8 feet on the northerly side, and
has no transportation related issues.
Finding: SDC 4.2-IOS(A)(I) says, "Streets shall ordinarily conform to alignments depicted in
TransPlan, the Regional Transportation Plan (RTP), applicable Refinement Plans, Plan Districts,
Master Plans, Conceptual Development Plans, or the Conceptual Local Street Map."
Finding: The Local Conceptual Street Map shows Booth Kelly becoming a local street,
extending from the west border to the east border of the West Wind Estates subdivision.
Finding: Lot 101 boarders Booth Kelly Road. There is presently no through street on the north
side of Lot 10 I, but it is on the Local Conceptual Street plan and is planned to have a crossing
intersection instead of the "T" intersection built now. (See below.) Westwind Estates presently
only has a short stub north of Lots 87 & 86. Extending this stub to the west as base line, the
future southern point of curvature of the curb at the southeast comer of Booth Kelly Road and
Holly Street intersection will be approximately 8 feet south of the south right-of-way line of
Booth Kelly Road.
Finding: SDC 4.2-120(C) states, "Driveways shall be designed to allow safe and efficient
vehicular ingress and egress as specified in Tables 4.2-2 through 4.2-5 and the City's
Engineering Design Standards and Procedures Manual and the Public Works Standard
Construction Specifications." The Public Works Standard Construction Specifications contain
Standard Drawing 3-19 which requires that driveway approach wings be a minimum distance
away from one foot from the projected property line. ,~ /f. JJ 1\

Finding: SDC Table 4.2-4 specifies "Minimum Separations Between a Driveway and the
Nearest Intersection Curb Return on the Same Side of the Street." For Single-family Residential
and Duplexes uses on local streets the required separation is 30 feet. The footnote for said table
gives four exceptions to this standard, none of which apply. However, it is the opinion of the
Transportation staff that the Conceptual Street Plan may not ever be implemented in this
particular area because of grade issues. If it is, the eastbound traffic along the Booth Kelly Road
will be slowed by the abrupt change in grade and any traffic turning south onto Holly Street will
be slower than average traffic. Because of these two combined views, some leniency on the 30
foot standard separation is deemed appropriate.
Reauired Condition: The driveway throat shall be no less than 4 feet and no more than 7
feet from the south property line. The driveway throat is limited to 12 feet wide. The
driveway apron shall comply with Standard Drawing 3-19, 3-20 or 3-21 of the Public
Works Standard Construction Specifications, whichever is applicable.
